Inverse z-Transform Partial Fraction expansion
www.cpp.edu › ~zaliyazici › ece308Z-Transform with MatLab-3 Z-Transform in Matlab Z-transform is defined as 0 ()()n n Xzxnz ∞ − = = ∑ or [X(z)= Z xn()] The inverse z-transform is denoted by x(n)= Z−1[ Xz()] MatLab Symbolic Toolbox gives the z-transform of a function Example: 1 ()() 4n xn= un 2 21 z Xz z = − >> syms z n >> ztrans(1/4^n) ans = 4*z/(4*z-1) >> syms z n ...
